Whereas a novel tension means is shown present such means also performs this function especially where as shown the axis of winding, extending more or less toward the direction of the draft, is also more or less horizontal: When the speed of the yarn is slow, and particularly when it is slowing, on the yarn passing the peak of the mass (arrow c Fig. 2) the mentioned length tends to fall by gravity, with production of slack, and since the preceding delivery of a convolution involved a twist in the yarn this twist tends to develop a kink or loop in the said length as heretofore explained, which kink becomes troublesome in subsequent manipulation of the yarn. If the filaments 8 are present they act to resist the travel of said length in its orbital movement and instead of such length at the down-moving side of the mass falling to produce slack, with consequent formation of a kink, it is left supported by one of the filaments, as indicated at d, for example, in Fig. 2.

Whereas in some of the appended claims I treat the spool or core and the fitting as together constituting supporting structure for the yarn mass and the filaments it is to be understood my invention also contemplates supporting means other than specifically that which is thus constituted.

Having thus fully described my invention what I claim is:

1. A device to be positioned at the delivery end of a wound yarn mass from which the yarn is to be drawn over-end fashion including an arouate series of resilient flexible filaments arranged to project from within to beyond a given orbit and a support circumscribed by said orbit and comprising members exerting clamping pressure on said filaments lengthwise of the axis of said orbit.

2. In combination, with structure to support a body including a wound yarn mass from which the yarn is to be drawn over-end fashion, said structure having a support to adjoin the delivery end of said body when supported on said structure, resilient flexible filaments supported by said support nearer to the axis of the mass than the periphery of such mass is to said axis and projecting free from their points of support through the orbit in which the yarn in being delivered travels rotatively.

3. The combination set forth in claim 2 characterized by said support including a disk-like portion substantially coaxial with the mass and having a diameter approximating that of said body at its delivery end.

4. A device of the class described including a series of resilient filaments all substantially radial to a common axis and supporting means for the filaments exerting clamping pressure thereon lengthwise of said axis and inwardly of their outer ends.

5. A device of the class described including a series of resilient filaments all substantially radial to a common axis and supporting means for the filaments including disk-like elements of less radial dimension than and exerting clamping pressure on the filaments inwardly of the outer ends thereof and there being a clear space between each said element and such series of filaments around the zone of clamping pressure.

6. Means for supporting a wound yarn mass from which the yarn is to be drawn over-end fashion and for controlling the orbital movement of the yarn including supporting structure and long resilient filaments supported thereby and all arranged in succession around the axis of the mass and in planes respectively crossing the path of orbital movement of the yarn at intervals which are wide relatively to the thickness of any filament and the space between each two adjoining planes being clear to permit the yarn when received therein to move freely from one to the other corresponding filament.

7. The means set forth in claim 6 characterized by said filaments being supported by said structure inwardly of said path.

8. The means set forth in claim 6 characterized by said structure including a disk-like portion substantially coaxial with and arranged at the delivery end of the mass and by said filaments flanking said portion and being supported by said structure inwardly of said path.
